I need many boxes and I have many drawers to fit them in. The goal of this project was to create a quick printing, low resource box that could fit various needs. They are suitable for holding very small components and printable without support.

The brackets will fit standard single wall cardboard. They are assembled with three pieces, one folded into a U shape and slotted into the L slats, and two smaller single walls. Score and fold with the grain for clean edges. If you're accurate enough, they should also stack. Double check the fit if you plan on using other mediums such as wood or plastic.
